Microsoft finally relents, releases Office app for iPad

SAN FRANCISCO — Microsoft has released an iPad version of its popular Office software suite, a breakthrough heralding a new era under a chief executive who promises to focus more on the devices that people are using instead of trying to protect the company’s lucrative Windows franchise.

Thursday’s unveiling of the much-anticipated iPad apps for Microsoft’s bundle of word processing, spreadsheet, and presentation software comes nearly four years after Apple Inc. released the tablet computer that has contributed to a steady decline in sales of desktop and laptop machines running on the Windows operating system.

Microsoft’s decision to relent to persistent demands to make its top-selling software application available on the world’s most popular tablet comes seven weeks after the Redmond, Wash., company anointed Sayta Nadella as its chief executive after being led for 13 years by Steve Ballmer.

The change in command gives Microsoft Corp. an opportunity to prove it’s a more nimble company adapting to evolution of computing instead of clinging to its old ways.

Nadella, who has been working at Microsoft for 22 years, emphasized that he felt rejuvenated since taking over as chief executive.

‘‘You see things from a fresh set of eyes and fresh perspective,’’ Nadella told a crowd of reporters gathered in San Francisco for his first major public appearance as CEO.

The Office app for the iPad represents a major step in the right direction for Microsoft, said FBR Capital Markets analyst Daniel Ives.

‘‘They finally looked in the mirror and realized they needed to go with the crowd in terms of iPads,’’ Ives said.

Like several other analysts, Ives thinks the Office app for the iPad could generate an additional $1 billion in revenue for Microsoft. Although the Office app is free to anyone who wants to read Office’s Word, Excel, and PowerPoint programs on the iPad, it will require a subscription to Microsoft’s Office 365 to create and edit documents on the device. The Office 365 subscriptions cost $70 or $100 annually, with the lower price placing more restrictions on the number and types of devices that can be used.

The Office 365 subscriptions also have been required to use Office apps built for the iPhone and Android phones last summer, so many iPad owners may already have one.

But millions of people with iPads probably haven’t had a reason to buy an Office 365 subscription until Thursday. Nearly 200 million iPads had been sold through the end of 2013, meaning about 5 percent of those device owners would have to pay for a $100 annual subscription to generate an additional $1 billion in revenue.

Microsoft hasn’t said how many Office 365 subscribers it has, but Nomura analysts Rick Sherlund estimates the number at anywhere at between 14 million to 24 million. He estimates that the annual subscription revenue is running at about $2.5 billion.
